Electrical Characteristics
This section provides the AC and DC electrical specifications and thermal characteristics for the chip. The
device is currently targeted to these specifications. Some of these specifications are independent of the I/O
cell, but are included for a more complete reference. These are not purely I/O buffer design specifications.
